Numerical investigation of transient thermal and fluidynamic fields in an executive aircraft cabin

The objective of the present work is the numerical simulation of the thermal and fluid dynamic fields in the cabin of an executive aircraft. A transient analysis is conducted on three-and two-dimensional models of an executive aircraft cabin and a comparison of the two approaches is provided. In the model, a global thermal conductance was considered to take into account both the external environment and the fuselage material. The results, provided in terms of graphs and contours, refer to the three-and two-dimensional models with inclined top inlets with respect to the vertical direction of an angle of 45°. A good qualitative agreement between the results of the two and three-dimensional models is detected.
